1. IN A SYSTEM FOR IDENTIFYING EACH OF A PLURALITY OF DIFFERENT WAVESHAPES, APPARATUS COMPRISING: A PLURALITY OF TRANSMISSION CHANNELS EQUAL IN NUMBER TO THE NUMBER OF SAID DIFFERENT WAVESHAPES, EACH OF SAID TRANSMISSION CHANNELS CORRESPONDING TO ONE OF SAID WAVESHAPES; SAMPLING MEANS FOR RECEIVING ANY ONE OF SAID WAVESHAPES AND A RESPONSIVE THERETO FOR DELIVERING A PLURALITY OF SIGNAL SAMPLES OF SAID WAVESHAPE TO ALL OF SAID TRANSMISSION CHANNELS; EACH OF SAID TRANSMISSION CHANNELS HAVING A PLURALITY OF MULTIPLYING ELEMENTS DISPOSED CHANNELS; EACH OF SAID PLURALITY OF MULTIPLYING ELEMENTS BEING ADAPTED TO MULTIPLY FOR AMPLITUDE TO A SIGNAL APPLIED THERETO BY A VALVE PROPORTIONAL TO THE AMPLITUDE OR A RESPECTIVE SIGNAL SAMPLE DELIVERED BY SAID SAMPLING MEANS WHEN SAID CORRESPONDING CHANNEL WAVESHAPE OCCUPIES A REFERENCE POSITION IN SAID SAMPLING MEANS TO PRODUCE MULTIPLIED SIGNALS OF A LIKE POLARITY; EACH OF SAID TRANSMISSION CHANNELS HAVING AT LEAST ONE ADDITIONAL MULTIPLYING ELEMENT DISPOSED THEREIN, EACH OF SAID ADDITIONAL MULTIPLYING ELEMENTS BEING ADAPTED TO MULTIPLY THE AMPLITUDE OF A SIGNAL APPLIED THERETO BY A VALUE PROPORTIONAL TO THE AMPLITUDE OF ANOTHER SIGNAL SAMPLE THAT MAY BE DELIVERED BY SAID SAMPLING MEANS WHEN A DIFFERENT CHANNEL WAVESHAPE OCCUPIES SAID REFERENCE POSITION IN SAID SAMPLING MEANS TO PRODUCE A MULTIPLIED SIGNALS OF A POLARITY DIFFERENT FROM THOSE MULTIPLIED SIGNALS PRODUCED BY SAID PLURAILITY OF MULTIPLYING ELEMENTS; EACH OF SAID PLURALITY OF MULTIPLYING ELEMENTS BEING COUPLED TO RECEIVE SAID RESPECTIVE ONE OF THE SIGNAL SAMPLES DELIVERED TO THE ASSOCIATED TRANSMISSION CHANNEL WHEN SAID CORRESPONDING CHANNEL WAVESHAPE OCCUPIES SAID REFERENCE POSITION IN SAID SAMPLING MEANS TO PRODUCE SAID MULTIPLIED SIGNALS OF A LIKE POLARITY; EACH OF SAID ADDITIONAL MULTIPLYING ELEMENTS BEING COUPLED TO RECEIVE ANOTHER ONE OF THE SIGNAL SAMPLES THAT MAY BE DELIVERED TO THE ASSOCIATED TRANSMISSION CHANNEL WHEN SAID DIFFERENT CHANNEL WAVESHAPE OCCUPIES SAID REFERENCE POSITION IN SAID SAMPLING MEANS TO PRODUCE SAID MULTIPLIED SIGNALS OF A POLARITY DIFFERENT FROM THOSE MULTIPLIED SIGNALS PRODUCED BY SAID PLURALITY OF MULTIPLYING ELEMENTS; MEANS IN EACH OF SAID TRANSMISSION CHANNELS FOR COMBINING ALL OF SAID MULTIPLIED SIGNALS PRODUCED BY THE MULTIPLYING ELEMENTS THEREIN WHEN A WAVESHAPE OCCUPIES SAID REFERENCE POSITION IN SAID SAMPLING MEANS AND FOR DELIVERING A CORRESPONDING COMBINATION SIGNAL; AND MEANS FOR SENSING THE COMBINATION SIGNALS DELIVERED BY ALL OF SAID TRANSMISSION CHANNELS TO DETERMINED WHICH ONE OF SAID DELIVERED SIGNALS HAS THE GREATEST AMPLITUDE AND FOR PRODUCING A SIGNAL IDENTIFYING THE ONE OF SAID TRANSMISSION CHANNELS WHICH DELIVERS SAID GREATEST AMPLITUDE SIGNAL.
